Intracellular fluorescence intensity evaluation of chitosan–noisome–paclitaxel–BODIPY 564/570. Fluorescence intensity was measured at 5 min and 24 h after incubation. Approximately 2× higher fluorescence intensity was observed in OV2008 tumor cells when compared to IMMC3 normal cells. Error bars: ± 1 SD. *Represents statistically significant difference (unpaired t-test, p < 0.05)
